Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592298, here are decompositions:

7 + 31592291 = 31592298
41 + 31592257 = 31592298
79 + 31592219 = 31592298
137 + 31592161 = 31592298
139 + 31592159 = 31592298
149 + 31592149 = 31592298
251 + 31592047 = 31592298
389 + 31591909 = 31592298

Showing the first eight; more decompositions exist.
